What a block foundation wall job involves

Foundation block wall installation in Columbia, MO means laying concrete block walls on poured concrete footings, so they carry your house and hold back the soil around your basement or crawlspace. At Blockworks Columbia Concrete and Masonry, I come out to the lot myself before anything gets priced.

Most folks who call about this are building a new house or an addition and want walls that stay dry and straight. The price moves with how long and tall the walls run, how deep the dig goes, how much steel and grout go into the block, and how much water protection your basement plans need, while the schedule turns mostly on the weather and on when your framer can set the floor on top. We're licensed and insured, and before work starts we check whether your address sits inside the City of Columbia or out where Boone County codes and building inspections apply, then take care of any permit paperwork the job calls for.

  • I look before anyone digs

    I come out to your lot myself, look at the grade and where water will run, and write the estimate, because a wall that misses the real problem just causes a new one.

  • A lead mason runs every day

    A lead mason runs our crew on site from the first course to the last, and I stop by to check the work and walk the finished walls with you.

  • In business since 2013

    We've been laying block, brick and stone since 2013, based in Columbia and working in Jefferson City, Fulton, Moberly, Boonville and plenty of other cities around them.

How we build a block foundation, step by step

I start by asking what you plan to do with the basement, because a room you'll live in someday needs a different plan for keeping water out than a space for the furnace and some boxes. Then our crew digs out, pours the concrete footings down below where the ground freezes, and lays the block course by course, checking level and line as the wall rises. With the walls up, we put the water protection on the outside face while it's still easy to reach. We don't push the soil back around the wall, what we call backfill, until the wall is braced or the first floor is framed on top, because a wall built to be held at the top can crack or even fail when the dirt leans on it first, and I'd rather leave the hole open a little longer than gamble on that.

Foundation walls are usually the first masonry on a new house, not the last. Once the yard's graded, a lot of people have us back for a new walkway from the drive to the front door, or the block and stone for an outdoor kitchen out back, and it helps that we already know how your lot drains.

What block foundation walls get built for

A full basement under a new house

Block walls go up course by course on site, so we can fit odd corners, window openings and a walkout door without waiting on forms, and we check the wall as it rises.

An addition that has to match

When you add a room onto a house with a basement, a block foundation lets the new floor line up with the old one, so the two parts of the house meet cleanly.

A crawlspace instead of a basement

If you don't need a full basement, a few courses of block on a footing make a crawlspace that keeps the floor up off damp ground and leaves room for plumbing.

A garage or shop foundation

A short block wall on a footing carries a garage or workshop, and it's simple to build up a few extra courses where your lot slopes away from the house.

  • Have your address ready

    Your address tells us whether the City of Columbia or Boone County handles inspections, so we know which office the permit paperwork goes through before we price the job.

  • Know how you'll use the basement

    Tell us if it'll hold storage, a workshop or living space someday, because that decides how we keep water out, and it changes both the plan and the price.

  • Your questions answered on site

    I'll walk the footprint with you, answer what you want to know about block, footings and drainage, and leave you a price you can compare against other bids.

Questions about block foundation walls

Here's what homeowners ask most before they build a block foundation, from cost and footing depth to waterproofing and the weather.

How much does a block foundation wall cost in Columbia, MO?

An installed block foundation wall across the US usually costs about $12 to $18 per square foot of wall, and that's a national figure, not our price. Yours turns on the wall's height and length, how deep the dig goes and how much waterproofing the basement needs. When you compare bids, ask whether each one includes digging, footings, waterproofing and backfill.

Does my new basement wall need waterproofing or just dampproofing?

If you'll ever live in the basement, plan on waterproofing, which is a step beyond dampproofing. One trade guide calls for it when soil drains slowly, the wall sits below the water table, drainage can't be counted on, or the basement holds living space. Heavy clay soil or a high water table can build water pressure against a wall below ground.

How deep do foundation footings go in Columbia, MO?

Footings go below the frost depth, the point where the ground freezes, so water freezing in the soil can't heave and damage them. A Columbia city council bill on the home building code lists a frost line depth of 30 inches. That's why the dig for a footing goes deeper than most people expect.

When is the best time to lay block for a foundation?

Mortar sets up best in humid weather with temperatures averaging above 40°F and below 70°F, so mild weeks suit block work best. When a hot, dry spell or a cold snap shows up in the forecast, we plan the block laying around it and line up the rest of your build to match.

Do block foundation walls need grout and rebar in the cores?

They should where soil pushing sideways on the wall is a concern, according to one trade guide, which says no mortar is strong enough there, so the hollow cores get filled with grout and steel bars called rebar. The same guide calls for Grade N block in foundations, not Grade S, since it bears more load and resists frost and moisture better.
